─ 3.1. Radiation Pattern

As the simulation Type has been set to None, multiple options are available within the Show Results menu: Far Field, Radiation Pattern, View Currents and View Charges.

Ther Radiation Pattern for the cut Phi=45º and Theta=30º can be shown by clicking on Show Results - Far Field - View Cuts. In this panel, on Options box, the user can add or delete new curves, in order to compare them. 

With the Export button, the values of this cut will be saved in a .txt file and with the Import button, new values can be imported in order to visualize them.

 

Radiation Pattern at Theta=30º

The 3-D pattern can be visualized by clicking on Show Results - Radiation Pattern - View 3D Pattern.

By selecting Enable Filtering in Filtering Range, the appropriated range for the color palette can be fixed.

Radiation Pattern

Any cut within the 3-D pattern can be also visualized by clicking on Show Results - Radiation Pattern - View Cuts. The figure below shows the Radiation Pattern for the direction Phi=0º.

Radiation Pattern at Phi=0º

The Current Density can be visualized by clicking on Show Results - View Currents. The next figures show three currents at different frequencies.

The 3-D Pattern can be visualized by clicking on Show Results - Radiation Pattern - View 3D Pattern.

3D Radiation Pattern

The Radiation Pattern for the cut Phi=45º has been shown by clicking on Show Results - Far Field - View Cuts.

Radiation Pattern cut for Phi=45º

The radiation pattern of the previous project will be imported, in order to check the effect of modifying the weight of the array elements in the radiation.

Click on Import  Series button and import the .txt files of the results of the previous project.

Comparison of the results for a phi=45º cut. Array with windowed weights (red line) and array with original weights (blue line)

Comparison of the results for a phi=30º cut. Array with windowed weights (red line) and array with original weights (blue line)

In this case, we can appreciate that the array with windowed weights has its lobes at a lower level.
